Sure would be nice to have a DVD burning program with sliders to line up the audio to the video. My video is a full 4 seconds ahead of the audio on DVDs. It's perfect when just playing the AVI files. I double click each AVI file, and they come up and run in perfect audio/video sync.There are 5 of them to merge into a DVD. But the 4 second error is there every time I burn those 5 AVI files to a DVD. I've burned 6 coasters with different DVD burning programs. Since the audio/video sync is such a pervasive problem, why doesn't a software engineer come up with this fine tuning sync software? I'd snap it up in a New York minute.
